Any person transported to the regional jail as provided for by the provisions of this section shall, upon conviction for the offense causing his or her incarceration, pay the reasonable costs of the transportation. The money is to be collected by the court of conviction at the current mileage reimbursement rate. The county commission shall allow the actual and necessary expenses incurred in serving summonses, notices or other official papers in connection with the sheriff's office.
